A metamodel-based optimization approach to reduce the weight of composite laminated wind turbine blades
(Elsevier, 2018-06)
In wind turbine blades, the complex resultant geometry due to the aerodynamic design cannot be modified in the successive mechanical design stage. Hence, the reduction of the weight and manufacturing costs of the blades ...
An optimization method based on the evolutionary and topology approaches to reduce the mass of composite wind turbine blades
(Springer, 2020-08)
The design of large and lightweight wind turbines is a current challenge in the wind energy industry. In this context, this work aims to present a novel methodology to reduce the mass of composite wind turbine blades by ...
Otimização de projeto aerodinâmico de pá de microgerador eólico empregando o algoritmo genético
(Universidade Tecnológica Federal do ParanáCuritibaBrasilGraduação em Engenharia MecânicaUTFPR, 2017-06-22)
To enable the spread of wind energy micro generation, it is necessary to create wind generators with accessible size and price. In this paper, it is proposed the creation of a computational tool to optimize the traditional ...
Modeling a lifting of a surface with an active smart flexible flap
(Asociación Argentina de Mecánica Computacional, 2012-11)
In the past years, the consumption of energy produced by wind turbines had an exponential growth. This requirement gave momentum to the development of larger turbines with the goal of producing more energy at the same site, ...
